Many animal shelters welcome old blankets and towels, which makes Blankets & Throws one of the nicest steps in Let It Fall.
Gather every throw, duvet and spare bed set in the house. Most homes have more than they need, usually in a cupboard nobody opens. Keep the ones you actually curl up with, plus a sensible number of spares for guests.
The rest has somewhere useful to go. Shelters use blankets and towels for bedding and cleaning, and plenty of them ask for exactly this kind of donation. Call or check their website first, because needs change and some only take certain items.
Log the donation from the Let It Fall screen and pick Donated as the method. If you're curious later, your stats will show how much of what you've cleared went to a good home rather than the trash.
And a cupboard with room in it means you can actually find the good blanket on a cold night.
